Last week I posted my project, the Spatialized Umbrella v01. 5 speakers and LEDs are mounted inside of the umbrella, around the users’ head, allowing for sound and light spatialization. The ‘raindrop’ samples play in a loop, each speaker playing their own unique raindrop. The LEDs light up the speaker playing at that moment. The tempo of the loop is controlled by a long-range Sharp Infrared range finder. The closer an object is to you, the faster the loop plays. If an object is close enough and a threshold is reached, a lightning sequence is triggered. Best part: COMPLETELY SAFE FOR USE IN THE RAIN.
I absolutely could not fit an entire Arduino in the canopy of the umbrella, especially because I need it to be able to close if I wanted this project to be viable at all. This (as well as cost) was the reason I chose to use a MapDuino for this application. Here are some images, in this form, I soldered a 28-pin IC socket to the PCB (bare, from radioshack) as well as the rest of the circuit, completely contained on the one board measuring less than half the size of a full Arduino board.
